Broadband antenna for wireless communications

Abstract

An antenna formable on a ground plane for wireless communications is disclosed. The antenna has a first structure spatially displaced from a ground plane. The antenna also has a second structure coupled to the first structure and extending away from the ground plane. The antenna further has a third structure configured for disposing at least a portion of the first structure between the third structure and the ground plane, the third structure being grounded to the ground plane and being spatially displaced from the second structure, the second structure and the third structure being inter-configured for electromagnetic coupling therebetween for forming a magnetic loop. More specifically, electromagnetic field generated by the first structure and the second structure electromagnetically couples the third structure for inducing generation of broadband electromagnetic waves from the first, second and third structures.
